PBS, PLA: Leej twg muaj peev xwm txhim kho ntau dua. Yuav PBS Hloov PLA
Tso lus
Piv nrog PLA, PBS muaj qhov ua tau zoo dua thiab qhov kub thiab txias, thiab cov txheej txheem synthesis yog yooj yim. Lub softening point ntawm PBS yog siab li 101 degree, thaum lub PLA yog tsawg li 58 degree.
PBS tuaj yeem siv rau hauv qhov kub ntawm -30 ~ 100 degree, uas tuaj yeem siv rau hauv cov dej kub npau npau. Txawm li cas los xij, vim qhov txwv ntawm qhov muag muag, daim ntawv thov teb ntawm PLA raug txwv rau qee qhov.
PBS muaj kev ua haujlwm zoo heev thiab ua haujlwm yooj yim dua PLA. Qhov sib txawv ntawm kev ua tau zoo yog ib qho ntawm qhov sib txawv loj tshaj ntawm PLA thiab PBS. PBS tuaj yeem ua tau ncaj qha rau ntawm cov khoom siv polyolefin ua tam sim no, thiab tsim nyog rau kev txhaj tshuaj molding, extrusion, yas nqus thiab lwm yam kev ua cov pa thiab tshwj xeeb. Raws li cov thev naus laus zis tam sim no, cov txheej txheem PBS hlwv tau ua tiav ntau dua, tab sis cov txheej txheem txhaj tshuaj tseem xav tau kev ua tiav.
PLA ua tej yam kev mob hnyav, tsis zoo adaptability, tsis tsuas yog xav tau kev hloov kho thiab hnyav ua ib puag ncig (qhuav ib puag ncig), tab sis kuj yuav tsum tau tshwj xeeb hloov cov khoom ua.
Lub ntuj degradation efficiency ntawm xyoob hmoov / PLA biodegradable composite khoom nyob rau hauv cov av yog kuj tsawg. Txhawm rau kom paub txog qhov ua kom zoo ntawm cov hmoov xyoob hmoov / PLA biodegradable composite khoom, qee yam kev ntsuas yuav tsum tau ua, xws li lub hom phiaj bioefficient degradation ntawm cultivated fungi, kab mob los yog microbial flora system, thiab lwm yam.
Kev siv cov hmoov xyoob hmoov los yog hmoov txhuv nplej siab rau kev hloov pauv yog qhov zoo los ua kom biodegradation tus nqi ntawm PBS. Tus nqi degradation ntawm PBS / xyoob hmoov sib xyaw yog siab dua li ntawm PBS tsis hloov kho, tshwj tsis yog rau PBS / xyoob hmoov sib xyaw nrog cov neeg sawv cev sib txuas.
